EQ (Equalizer)
This module provides you with a high-pass filter and four bands of equalization that you can use to
shape the sound of your audio signal by cutting and boosting certain frequencies.
HPF (High-Pass Filter)
Turns on the high-pass filter, which reduces very low frequencies (below 80 Hz).
Useful for getting rid of noise caused by air conditioners, passing cars or other low-
frequency rumble (great if you're recording at home).
Turns off the high-pass filter.
LOW
Boosts or cuts frequencies below 150 Hz in 1 dB steps from -12dB to +12dB.
Turns off the LOW EQ band.
LO MID
Boosts or cuts the 700 Hz range in 1 dB steps from -12dB to +12dB.
Turns off the LO MID EQ band.
HI MID
This band is a parametric band at 2.5kHz with a Q of 1.5.
Boosts or cuts the 2.5 kHz range in 1 dB steps from -12dB to +12dB.
Turns off the HI MID EQ band.
HIGH
Boosts or cuts all frequencies above 5 kHz in 1 dB steps from -12dB to +12dB.
Turns off the HIGH EQ band.
EDGE
This is a filtered limiter that gives your acoustic guitar a bright, edgy sound. This effect works by taking
the original signal, filtering out all frequencies that fall below 2kHz, feeding that into a limiter and then
mixing it back with the original, unfiltered, unlimited sound.
Increasing amounts of edge.
Turns off EDGE.
HUM CANCEL
The hum canceller eliminates unwanted low-end hum by eliminating the frequency that contains the
hum (60Hz). Unlike the high-pass filter, this mode allows you to control how much noise you want to
eliminate.
Increasing levels of hum elimination (60Hz harmonic notch filters).
Turns off the hum canceller.
